Answer:
x=3 y=5/2
Step-by-step explanation:
1. 0.5x + y =4
2. 0.5x-y=-1
subtract the 2nd equation from the 1st
0.5x cancels out
2y = 5
y = 5/2
subs y = 5/2 into any one of the equations to find x
0.5x + 5/2 = 4
x = 3
subs to see if right:
(0.5 x 3) +5/2 = 4
(0.5 x 3) -5/2 = -1
Answer:
Step-by-step explanation:
To find the zeros, set y=-4(x - 3)2 + 8 = 0. Then -4(x - 3)^2 = -8, and:
4(x - 3)^2 = 8. Dividing both sides by 4 yields (x - 3)^2 = 2.
Taking the square root of both sides yields x - 3 = ±2, so that
x = 3 ±2, or x = 5 and x = 1. These are the zeros. The correct interpretatioon is A: where the daily profit is $0.
9ft to 6 yard can be written as a fraction 6/9
6/9 = 2/3
3 ft to 2 yards is the simplest form of this ratio
Answer:
The equation is y = -1/4x + 4
